Thanks Flargle,
In searching threads, it looks like you've been a good resource for folks here.
I found some used (affordable) 1.5s for my mtn bike and am trying to figure just one more thing out:
At what point could UCI rules even affect me? I see in races for elites, UCI doesn't allow over 35mm tires. Unless I turn into someone else in the near future, I won't be racing elite. So will using 1.5s limit me in any way in terms of entering cat 4 races? I just want to make sure there are no cat 4 races I'd miss being able to do because of tire size. I looked over the registration info. for a bunch of races and couldn't clearly figure this out. Thanks again.
